HA4850F

Solid State Relays

A solid state relay is an electronic switch/control device that controls connection of electric current to other circuitry. It utilizes opto-electronic principles to achieve switching of power from one side to the other. Generally, the device comprises two main components: an input and an output section. The former can be connected to the power source while the latter handles the power to the load. Solid state relays have been used in numerous industrial applications because of their reliability and relatively low cost compared to other electrical relays.

HA4850F Application Field and Working Principle

HA4850F is a type of solid state relay (SSR) from Shenzhen Hongan Automation Co., Ltd. It offers cost-effectiveness and high-performance, so it is widely used in industrial control systems. The HA4850F relay provides a zero-crossing trigger circuit, which can allow the relay to switch without generating an arc in the circuit, thereby guaranteeing the high reliability of the application.

The HA4850F utilizes 35A current which is suitable for voltage levels between 12 and 48 volts AC. When it comes to current capacity, this relay can manage load current upwards of 40A-AC1. The relay can be used to interconnect current up to 15kW. It also has a maximum voltage of 380VAC and a maximum switching power of 7.5kW. The small size and weight facilitates ease of installation and maintenance.

The HA4850F SSR is driven by a bipolar transistor. Basically, when the input control circuit triggers the SSR, the light-emitting diode inside the SSR is enabled to deliver light that closes the main output loop of the SSR. This, in turn, allows the current to flow through the load and thus has the desired effect. If the load disconnects or the input control circuit disconnects, then the loop will be opened, deactivating the output of the SSR.

In general, the HA4850F SSR is suitable for applications that require frequent switching of AC motors and other accessories. The HA4850F also has a compact structure and is applicable for a wide range of control systems. Moreover, its long-term stability is guaranteed and it has a robust design to enhance the safety of the job. In addition, the device comes with two LEDs, one for indicating the input state, and the other is for indicating the output state.

The HA4850F is a well-designed and highly advanced relay to facilitate use in industrial settings. The device affords reliable performance and significant cost savings. Its application field is vast given its multi-functional features and is a perfect choice for industrial control systems.
